Section 1: Listing of Safety Precautions

The following Safety Precautions must be observed when operating or servicing this surgical lighting system. WARNING indicates the potential for personal injury and CAUTION indicates the potential for damage to equipment. For emphasis, certain Safety Precautions are repeated throughout the manual. It is important to review ALL Safety Precautions before operating or servicing the unit.

Strictly following these Safety Precautions enhances your ability to safely and effectively utilize the unit and helps the customer avoid improper maintenance methods which may damage the unit or render it unsafe. It is important to understand that these Safety Precautions are not exhaustive; customers are encouraged to develop their own safety policies and procedures to enhance and compliment these Safety Precautions.

WARNING – ELECTRIC SHOCK AND BURN HAZARD:

Disconnect all utilities to lighting fixture before servicing. Do not install the lighting fixture unless all utilities have been properly locked out. Always follow OSHA Lockout-Tagout and electrical safety-related work practice standards. (See 29 CFR 1910.147 and .331 through .335.)

Do not remove covers or perform service other than as described in this equipment manual. Refer servicing to qualified service personnel. (Maintenance Manual P764330-226.)

WARNING – EXPLOSION HAZARD:

Do not use lighting fixture in the presence of flammable anesthetics.

WARNING – PINCH AND CRUSH HAZARD:

Do not pinch fingers between the structural plate and the vertical tube as the assembly is lifted.

The safety ring must be installed.

Pinch points are created during extreme articulation of the suspension system. Do not place hands on or near the suspension knuckle during lighthead articulations.

WARNING – IMPACT HAZARD:

Do not remove tension screw from the spring arm joint until the lighthead has been securely installed onto the spring arm. Note: This warning applies at both installation and de-installation procedures.

WARNING – PERSONAL INJURY HAZARD:

Do not attempt to replace the lamp unless power is turned off and the lighthead has cooled sufficiently.

Do not attempt to clean lighthead unless power is turned off and the lighthead has cooled sufficiently.

Do not remove monitor-arm safety pin until monitor is installed.

Monitor extension arm must have monitor (or equivalent counterweight) installed to keep arm in required positions while installing sliding guards.

Avoid looking directly at high-intensity light, whether at the lamp or directly at the lighthead. Eye injury may result.

1-1

764330-226

WARNING – POSSIBLE PATIENT INJURY HAZARD:

Failure to engage the lighthandle cover completely may result in cover falling from lighthead during the procedure.

WARNING – BIOHAZARD:

Sterile disposables are intended for single use only.

Universal precautions must be observed when disposing of any single use disposable item.

WARNING – DISPOSAL HAZARD:

This product contains materials which may require disposal through appropriately licensed and permitted hazardous waste management firms.

CAUTION – POSSIBLE EQUIPMENT DAMAGE:

Use of any disinfectant solution OTHER than those listed below may cause discoloration or deformation on the polycarbonate lens surface: Coverage® Spray HBV, Coverage® HBV Concentrate, T.B.Q.®, or Coverage Plus®, CoverageTM Spray Disinfectant Cleaner, or Germicidal Cloth. Cleaning solutions other than those listed have NOT been tested for compatibility or effectiveness. Always follow manufacturer instructions for concentrations and use of cleaning products.

Use only recommended cleaning/disinfecting and/or anti-static agents on this light. Some degree of staining, pitting, and/or discoloration could occur if a phenolic-, iodophor-, or glutaraldehyde-based disinfectant is used on the surfaces of this light. Also, use of alcohol or aerosol spray cleaner/disinfectants (e.g., Lysol®) containing a substantial amount of alcohol in the formula can damage the polycarbonate lens.

Prevent leakage of fluids into interior of lighthead.

Avoid discoloration of control center keypad and display. Do not clean control center with Betadine® solutions or allow such solutions to contact keypad and display surfaces.

Do not scratch optical coating on accessible portions of optic assembly when cleaning; always wear rubber gloves and use only a clean, white, lint-free cloth when wiping internal surfaces.

Appropriate components of this lighting system have been tested and found in compliance with IEC 60601- 1-2 (1st Edition 1993-04), Medical Electrical Equipment – Part 1: General Requirements for Safety; Electromagnetic Compatibility (EMC). There is, however, a potential for electromagnetic or other interference between this equipment and other devices. Should you experience interference, relocate this device or minimize the use of the affected equipment while this device is in operation.

Do not touch the glass portion of the lamp with bare fingers. Skin oils can cause deterioration of material leading to possible failure of the lamp.

Accurate measurement and calculation in finding the point where the first hole is drilled for the safety ring is of critical importance in correctly installing the vertical tube. Check all measurements and calculations twice before drilling the first hole.

Do not pinch wires that exit the vertical tube as the assembly is lifted. Gently route wires from the vertical tube out of the way as the suspension system is lifted into place.

1-2

764330-226

CAUTION – POSSIBLE EQUIPMENT DAMAGE (Continued):

Do not pinch wire on the ceiling structure or vertical tube.

During all mounting steps, ensure wires are not pinched between mechanical components of suspension, spring arms, or lightheads.

Harness connectors must be slipped into expandable sheathe before routing through monitor yoke.

•Failure to use sheath may cause connector damage during routing.

•Slip sheathe only far enough onto the harness to protect connector bundle. If sheathe is slipped too far onto the harness, removing it after routing may be difficult.

Do not touch glass portion of lamp with bare fingers. Skin oils can cause deterioration of material leading to possible failure of the lamp.

Sliding guards may be damaged if not installed properly into internal grooves.

On early light systems, the wire clamp must be loosened to allow the wiring within the vertical tube to be free.

Section 3: Operating Instructions

3.1 GENERAL INSTRUCTIONS

The wall-mounted Harmony™ LA Control Center allows the user to adjust the lighthead intensity level (brightness) by pressing a membrane switch (or “button”). An identifying number on the control display corresponds to the same number on the lighthead suspension arm. Additionally, each lighthead has its own “onboard” intensity controls, located on the above the lighthandle adjacent to the lens. These controls are usually referred to as the surgeon’s control buttons or as the surgeon’s control. (See Figure 3-2.)

3.1.1 To Adjust Lighthead Intensity Levels:

WARNING-EXPLOSION HAZARD: Do not use in the presence of flammable anesthetics.

1.Press ON touch pad.

2.Intensity levels for one or two lightheads can be controlled from one control center. A lighthead’s surgeon’s control buttons adjust the intensity level for that lighthead.

Important: Avoid control center faults. Do not continuously press and hold any control center buttons for more than 15 seconds.

3.1.2 Control Center

WARNING-EXPLOSION HAZARD: Do not use in the presence of flammable anesthetics.

See Figure 3-1.

1.Use the “Select Light” touch pads to move the display indicator up or down until it aligns with the appropriate lighthead.

2.Once the lighthead is selected, press either the button to increase light intensity level, or the button to decrease light intensity level.

3.If “All Lights” is selected, intensity for all lightheads in the system is increased or decreased simultaneously.

NOTE: For longer lamp life, use lowest intensity level suitable for surgical procedure.

2.Press any of the surgeon’s control buttons molded with “+” symbols to increase the lighthead intensity. Press any of the surgeon’s control buttons molded with “-” symbols to decrease lighthead intensity.

NOTE: For longer lamp life, use lowest intensity level suitable for surgical procedure.

3.To turn lighthead OFF.

a.At the control center: press the “Select Light” button until indicator points to the appropriate lighthead on the display. Press the “Decrease Intensity” button until the light goes out.

b.At the lighthead, press and hold any of the “-” membrane buttons untilthe light goes out.

NOTE: Press the decrease intensity button (-) on the lighthead surgeon’scontrol for an additional 5 seconds, to turn off all lightheads in the system.

3.2HARMONY LA 500 LIGHTHEAD LAMP FAILURE INDICATIONS

The main display screen on the control center indicates lamp status for the system lightheads. The display indicates the status of both the primary and secondary lamps for each lighthead. A failed lamp should always be changed at the earliest opportu-

nity.

A Lamp Status LED is located on the lighthead (see Figure 3-3). If this LED is flashing, it indicates that the lighthead is using the backup lamp and the primary lamp should be replaced.

Check the lamp status LED each time the surgical light is used.

A secondary lamp inside Harmony LA 500 lightheads automatically turns on when the primary lamp fails.

If the lamp status LED is blinking, replace the failed lamp(s). (See Lamp Replacement, Section 6.) After the lamp is replaced and power restored to the lighthead, the primary lamp lights, the LED stops blinking and the graphic display changes to “lamp ready.”

3.3HARMONY LA 300/500/700 LIGHTHEAD POSITIONING

CAUTION: Do not bump lightheads into walls or other equipment.

Lightheads can be positioned by using either the sterile handle, or by grasping the non-sterile handle around the lighthead housing. The following two paragraphs describe the positioning characteristics of the lighthead from outside or within the sterile field. To optimize shadow control, position the lighthead as appropriate before starting the intended surgical procedure.

Lighthead may (1) rotate continuously around vertical suspension tube; (2)rotate continuously around central hub; (3) rotate continuously about suspen-

sion arm; (4) tilt forward or backward in yoke approximately 310°; and (5) move up or down by pivoting at suspension elbow 15° up, and 85° down until vertical tube and suspension arm describe a straight line.

Monitor arms are capable of the following articulations: (1) rotate 300° at the central or secondary spindle; (2) rotate 330° at the horizontal extension arm; (3) rotate 320° a the yoke transition; (4) move up or down by pivoting at spring arm knuckle 20° up, and 40° down. Flat panel yoke also allows (5) tilt forward 15° or backward 75° in yoke. Additionally, the flat panel yoke can be rotated for either portrait or landscape display. See Figure 3-4.

NOTE: Typical lighthead positioning is above and slightly behind the surgeon’s right or left shoulder.

3.5LIGHTHANDLE AND LIGHTHANDLE COVER

3.5.1Installing and Using Lighthandle and Lighthandle Cover

WARNING – POSSIBLE PATIENT INJURY HAZARD: Failure to engage the lighthandle cover completely may result in cover falling from lighthead during the procedure.

Lighthandles are used to position Harmony LA 500 lightheads, allow access to intensity control on each lighthead, and to adjust lighthead pattern size. To

3-4

764330-226

avoid accidental contact with the non-sterile surgeon’s control buttons, the lighthandle should always be used with a disposable, sterile lighthandle cover (available separately from STERIS→).

•If the lighthandle adapter is not already in place, align the tab on the adapter with the channel in the mounting ring and thread the adapter in until fully engaged. (See Figures 3-6a and 3-6b.)

•Prior to starting a procedure, ensure that the lighthandle is in place. Install the lighthandle by threading onto the adapter and firmly tightening. (See Figure 3-6c.)

•Remove the sterile lighthandle cover from its packaging and install onto the lighthandle. (See Figure 3-6d.)

•To ensure the lighthandle cover remains in place during the procedure, the groove in the cover must be fully engaged with the groove in the lighthandle.

•The lighthandle can be removed for cleaning or sterilization by unscrewing it from the handle adapter. The lighthandle can be sterilized using standard hospital cycles. Do not use the lighthead during a sterile procedure unless a disposable cover is installed on the lighthandle.

3.5.2METAL STERILIZABLE HANDLE

WARNING-STERILITY ASSURANCE HAZARD: Do not use the surgeon’s control buttons unless a disposable sterile cover is installed. If the sterilizable lighthandle (metal) is used without a disposable cover, the surgeon’s control buttons are not protected by a sterile covering.

The metal sterilizable handle is used to position the Harmony LA lighthead and to adjust the light pattern size. The sterilizable handle may be used in place of a disposable sterile lighthandle cover.

The plastic lighthandle should be removed prior to installing the metal sterilizable handle. To do so,

simply unscrew it from the threaded handle adapter.

Prior to starting a procedure, install a clean, sterilized metal handle by screwing it onto the threaded handle adapter. Ensure handle is firmly tightened prior to use. The gap between the flange on the metal steriliizable handle and the surgeon’s control buttons prevent accidental contact with the non-sterile surface of the buttons.

The metal sterilizable handle can be removed for sterilization by unscrewing it from the adapter.

The metal sterilizable handle can be sterilized using standard hospital cycles steam cycles intended for lumens. Always sterilize handle between surgical procedures.

3.10VIDEO CAMERA OPERATION NOTE: At extreme wide angle, the image field pos-

The optional video camera is integrated into a removable handle that can be fitted to any Harmony LA 500 or 700 lighthead. Whenever the video option is used, a separated sterile disposable cover must be fitted over the camera before each procedure. This cover allows the camera to be grasped and used in the same way as a standard handle, including positioning the lighthead for optimal illumination, adjusting lighthead intensity and pattern size, as well as positioning the video image field for the best view of the procedure. The sterile cover must be removed from the camera and discarded after each procedure.

Video and control signals are turned on or off at the control center; any of the optional remote control units (see below) provide similar control functions. The control center also provides additional control for video brightness and contrast, color gain, stillimage capture and time and date display.

Three optional remote devices can control camera functions: a hand-held wireless control, Hermes voice-activated control (verbal commands and handheld pendant), or a foot control.

The control center functions by transmitting signals via a control cable to the camera located in the lighthead.

The optional wireless control functions by transmitting infrared signals to the control center. To initiate camera functions with either control, press the appropriate touch pad on the control face panel. The hand-held control’s IR (infrared) transmitter must be within approximately 15 feet maximum and 50° of the control center receiver. The control touch pads are used to control the following camera functions:

Zoom–for determining the level of detail visible in the image field. The Zoom function adjusts the image field continuously between two extremes:

+(Telephoto). At extreme telephoto, the camera captures an image showing great detail in a small area.

NOTE: At extreme telephoto, any motion of the lighthead/camera will be exaggerated (jerky). The field of focus has little depth at this extreme, forcing the Auto Focus function (if enabled) to refocus the camera when any object (such as a hand) enters the image field, or if camera position is adjusted. The camera is also sensitive to light level changes at extreme telephoto.

–(Wide Angle). At extreme wide angle, the camera captures a large, image with less detail than telephoto.

sesses a greater depth of focus and less sensitivity to light level changes.

Rotate–Use this function to change orientation of the video field. Image field can be rotated in either clockwise or counterclockwise directions.

Bright–Use this function to affect the overall brightness (or darkness ) of the video image. The Bright control can be set to adjust itself automatically.

Manual Focus–Use this function to manually set the focus for close-up shots or other special applications. The Auto Focus function must be toggled off to enable manual focusing. Adjust the clarity of focus by pressing the + or – touch pads.

NOTE: + touch pad moves the lens slightly closer to subject; – touch pad moves the lens slightly away from subject.

Auto Focus – Use this function to toggle Auto Focus on or off. When Auto Focus is ON, the camera automatically focuses on the object in the image field closest to the camera lens. When Auto Focus is turned OFF, the camera maintains focus on the last object upon which it was focused, until Auto Focus is turned back on.

NOTE: It may be necessary to toggle Auto Focus OFF when using the camera at extreme telephoto (close up), to prevent the camera from refocusing on hands and other objects introduced into the image field while videoing procedures.

Red Gain/Blue Gain – These controls are used to adjust image color settings, and are intended to allow the user to compensate for changes in color temperature provided by differing light sources. The gain control can be set to adjust automatically.

3.10.1HERMES-Ready Control Center

The Hermes Control Center functions by transmitting signals through an interface cable connected to the wall control. When used, the interface cable should be routed to avoid surgical personnel foot traffic. The control center is intended to allow personnel within the sterile field to operate all camera functions using verbal commands or a hand-held pendant. Refer to the Hermes operating manual for more information.

3.10.2Optional Foot Control

The foot control functions by transmitting signals through a cable connected to the control center. When the foot control is used, the cable should be routed to avoid surgical personnel foot traffic. The foot control is intended to allow personnel within

3-10

764330-226

the sterile field to operate the zoom and rotation functions of the camera.

Foot control is used to control zoom and rotation functions. Press on appropriate sides of foot pedals to activate foot control functions. Functions controlled through the foot control unit are identical to those controlled through the optional hand-held wireless control or control center.

3.11GUIDELINES FOR MAXIMIZING VIDEO IMAGE

The following steps will aid in maximizing video imaging effectiveness.

1.Energize the light at medium setting on the control center, and position the lighthead approximately 39" (1000 mm) from the surgical site.

2.Using the hand-held remote, or the control center, zoom in or out (+ or -) until the desired image fills the viewing screen of the monitor.

NOTE: Zooming completely out causes image distortion within the illuminated area.

3.If the light pattern (white circle) does not fill the monitor’s screen (shaded square), the image inside the pattern will be distorted.

4.Reposition the camera to orient the focal point (center of the desired image) at the center of the viewing screen.

Adjust zoom and rotation as needed:

5.The camera may be zoomed to the full 10x zoom and rotation orientation adjusted as needed.

6.Clockwise and/or counterclockwise orientation is adjusted by using the curved arrow(s) on the hand-held control, the control center or the optional foot control.

3.11.1Engage Manual Focus

As instruments are introduced to and removed from the surgical field, the auto focus will attempt to focus on the nearest object, possibly causing the image to blur intermittently. To prevent this effect, once the camera has been positioned and focused onto the surgical site, the manual focus mode may be engaged to maintain image clarity during the procedure.

For deep cavity illumination, it may be necessary to engage the manual focus to focus beyond the nearest object (i.e., the surface area surrounding the incision) so that the desired image can be viewed clearly.
